				 The 
				chief of space operations said a direct line of communication 
				between the Space Force and its Chinese counterpart would be 
				valuable in de-escalating tensions but that the U.S. had not yet 
				engaged with China to establish one. 
				 
				"What we have talked about on the U.S. side at least is opening 
				up a line of communication to make sure that if there is a 
				crisis, we know who we can contact," Saltzman said, adding that 
				it would be up to President Joe Biden and the State Department 
				to take the lead on such discussions. 
				 
				The comments come as the U.S. Space Force looks into 
				establishing a branch in Japan, as China's military ambitions in 
				the Indo-Pacific unnverve its neighbors and the war in Ukraine 
				spotlights the importance of space capabilities in warfare. 
				 
				Japan has been especially concerned about Taiwan and any lessons 
				China may have drawn from Russia's invasion of Ukraine a year 
				ago. China, which views democratically governed Taiwan as its 
				own territory, has not renounced the use of force to bring the 
				island under Beijing's control. 
				 
				Saltzman, who held talks with top Japanese defense officials in 
				Tokyo on Monday, confirmed that the space force was exploring 
				the potential establishment of a local headquarters in Japan.
				 
				 
				He did not elaborate on the location or the purpose it would 
				serve, but did say it could look similar to a branch established 
				in South Korea in November last year. 
				 
				Saltzman added that deeper cooperation with like-minded 
				countries including Japan would be crucial in being able to 
				monitor and understand activity in the space domain to deter 
				China and counter 'grey zone activities' such as jamming 
				satellite signals.  
				 
				"We have to be able to have those indications and warnings and 
				see what they're doing and call them on the intent. Just being 
				hypersensitive so we don't fall prey to grey zone activities," 
				Saltzman said. 
				 
				The U.S. Space Force, founded in 2019, also does not have a 
				direct line of communication with its Russian counterpart.
